Little is known about the effect of pulsed electromagnetic fields (PEMFs) as an option for preventing osteoporosis. This study sought to investigate the effectiveness of PEMFs for the management of primary osteoporosis in older adults. We searched databases from the inception to date to target trials examining the effects of PEMFs compared to placebo or sham or other agents for the management of primary osteoporosis for a meta-analysis using random effects model. Eight trials including 411

PEMFs was non-inferior to conventional pharmacological agents and exercise respectively in preventing the decline of Bone Mineral Density (BMD) at the lumbar (MD 8.76; CI -9.64 to 27.16 and MD 1.33; CI -2.73 to 5.39) and femur neck (MD 0.04; CI -1.09 to 1.16 and MD 1.50; CI -0.26 to 3.26), and significantly improving balance function measured by Berg Balance Scale (BBS) (MD 0.91; CI 0.32 to 1.49) and Timed Up and Go test (MD -3.61; CI -6.37 to -0.85), directly after intervention. The similar trends were observed in BMD and BBS at 12- and 24-weeks follow-up from baseline. PEMFs had positive effects non-inferior to first-line treatment on BMD and better over placebo on balance function in older adults with primary osteoporosis, but with moderate to very low certainty evidence and short-term follow-ups. There is a need for high-quality randomised controlled trials evaluating PEMFs for the management of primary osteoporosis.
